Sending the same email to many separately

I may have asked this before, but here goes.

I have one email that I want to send to several people, but rather than having it sent to many people, I want each individual to think that I sent it to him/her individually. However, I don't want the hassle of having to resend it 20 times. Is there any way you can do this at once ... select 20 people, but have Outlook churn out 20 separate emails?
